void GW.set d3 fcn(geo scene sc, void (∗f)(geo scene gs, d3 window& W,
GRAPH & H))
sets a function for computing 3d output. The parameters
of the function are the geo scene for that it will
be set and a function pointer. The function f will get
the scene for that it was set and the reference to a
d3 window that will be the output window.
D3 FCN
GW.get d3 fcn(geo scene sc)
returns the function for computing 3d output
that is set for scene sc. The returned function
has pointer type void (∗)(geo scene, d3 window&,
GRAPH &).
GeoWin can be pined at a point in the plane. As standard behavior it is defined that
moves of geometric objects will be rotations around the pin point.
bool GW.get pin point(point& p)
void GW.set pin point(point p)
returns the pin point in p if it is set.
sets the pin point to p.
void GW.del pin point( ) deletes the pin point.

GW.add help text(string name)
adds the help text contained in name.hlp with label
name to the help menu of the main window. The
file name.hlp must exist either in the current working
directory or in $LEDAROOT/incl/Help. Note that
this operation must be called before gw.display( ).
GW.add special help text(string name, bool auto display = false)
adds one help text contained in name.hlp to the
menu of the main window. The file name.hlp must
exist either in the current working directory or in
$LEDAROOT/incl/Help. Note that this operation
must be called before gw.display( ). If auto display is
true, this help text will be displayed, when the main
window is displayed.

int GW.get limit(GeoEditScene ∗ es)
template
returns the limit of edit scene es (a negative number
will be returned, if there is no limit).
